Economics In One Lesson - Short easy read and probably the single best book on economics ever written.
Fiat Money Inflation in France - Written around a century ago covering events and policy prior to that. Reads like a current WSJ article. Free download available on mises.org I think. Suprisingly easy read too.
One Second After - A military historian takes the federal DoD/Congressional EMP commission report (hardly a "conspiracy theory" when its 100% government recognized and validated) and writes a novel about his small town going through the government report as a blueprint for what the US government has already modeled.
Charlie Wilson't War - the movie was insulting to the bredth and depth of the book. I know its fashionable to say that about everything, but for this book its especially true.
World War Z - someone above mentioned that and they are right about the movie; its irrelevant and not even related to the book. Cool thing about the book is that its a compillation of numerous shorter stories from multipile perspectives of the same event. Also keep in mind that the author has been invited numerous times to speak at military war colleges etc. Generals and admirals sit down and actually listen to him.
